Hello, everyone.
The engine is generally healthy and what bugs me the most, has JUST been overhauled by a good mechanic, which included cleaning the carb, after which it started on 1-3 pulls and ran like magic.
Today I went fishing for the first time after not using the boat for about 3 weeks. The engine started fine (with 2/3 choke), I let it warm up a bit, with little-to-none choke. Idle was a tiny bit rough, but nothing major. When I set it on idle for the first time, it ran for about 3 minutes and died. Since then I could only start it with either choke or some throttle and it'd always die quite soon on idle or close to idle. When I try to start it warm with no choke, it'd sound as if it catches and dies off immediately.
The plugs are 1 month old and adjusted, oil's in order, no detectable problems with the prop or anything else.

I have a suspicion it might be either condensate or some grit in the fuel tank, which was stored in a rather damp place for 3 weeks, half full (although tightly closed). What should I check and is there a way to condition the fuel somehow to remove condensate and clean out eventual b/s from the carb without major mechanical work (I really don't want to pull the boat ashore before autumn)?

Thank you!

probably only from Deutz but you can get the information from workshop manuals for Deutz trucks as the engines are basically the same in construction

Don't panic. There are a number of quick steps you can run through before you dig out the receipt and call the professionals.

1. Check the Fuel

We know; it's like being told to check that the kettle is plugged in. But one of the most common reasons for portable generator failure is simply that it might not have sufficient fuel. Especially if the last time you used it was last year. As well as checking the quantity of fuel, be sure to check the fuel quality as fuel can degrade while in storage. If this has happened and it has clogged up the engine, you might need to call a mechanic for help.

2. Check the Oil

Many portable generators feature automatic oil checks and will shut down automatically if the oil level becomes too low. Check the oil level with the dipstick and if necessary, add oil to meet the full level.

Yes, absolutely you need a fourth wire as a neutral wire if it is a 3 phase connection other wise you can manage with the single phase four wire system.

All automatic battery chargers in the automotive market today have some sort of voltage regulation to prevent overcharging the battery. The rate of the flashing is dependent on the battery type, its rated capacity, the degree of discharge, its age, the temperature, as well as the amperage rating of the battery charger.

If the charger's green LED begins blinking when you connect the charger clips to the battery, the amperage in-rush current to the battery is reaching the pre-set shut-off voltage and the charger is shutting down. The voltage will drop as soon as the charger shuts down, turning the charger back on. This may also mean the charger has detected a battery problem - for instance, its ability to take or hold a charge. Sometimes a battery may be sulfated (accumulation of lead sulfate on the battery plates), and the sulfation is creating a high resistance to the current flow (ability to accept a charge). Or, perhaps the battery is deeply discharged (below 8-volts).

The most common cause of portable generators failing to produce electricity is from the loss of residual magnetism.

Generators work by moving electrical conductors through a magnetic field. Your generator does not have magnets. The magnetic field is created by taking some of the generator output voltage and converting it to DC and feeding it to a coil to make an electromagnet.

When there is a small amount of magnetism left over from the last time the generator was running, it is called residual magnetism. The little bit of magnetism is enough to produce a small amount of electricity. This small amount of electricity is needed to create an even stronger electric magnet. As the engine turns this magnet moving its electric field, through the stator windings, your generator produces even more power.

When the residual magnetism is lost, the generator will produce no power at start-up. This residual magnetism can be lost naturally from not being used or from the load on your generator being connected when the generator is shut off. It can also happen from running a generator with no load for too long.

Generators need to work and it helps maintain that residual magnetism. When they are running, a load should be connected to it. It helps create an even stronger magnetic field. Before you shut it off, turn off the switch or breaker to disconnect the load. If you shut off a generator with the load connected, it can essentially drain or demagnetize the electromagnet. Try and avoid running out of fuel.

How to fix it:

There are a few methods of restoring a generator residual magnetism

12 Volt Generator Battery Method

Locate the voltage regulator for your generator.
Unplug the two wires that connect to the generator brushes. Normally one is red and the other is black or white.
Connect the black or white to the generator ground battery terminal.
Plug in a light, turn on the generator breaker or switch and start the motor.
Connect the battery +12 volts (red cable) to the red wire on the terminals you removed for three seconds.
Remove your wires and replace the plug. The generator should now be producing power again.

burned, dress smooth with file or fine stone. Do not
use emery paper or emery cloth. Measure gap with
thickness gauge; gap points at .020-inch (0.51 mm).
Ignition breaker points, Figure 16, must be correctly
gapped. Crank engine to fully open breaker points
(1/4 turn after top center). Loosen locking screws (A)
and turn cam (B) tQ adjust. Tighten breaker points
and recheck gap.
Ignition points should break contact just as the 20-
degree timing mark aligns with the flywheel timing
mark. Final timing is corrected by properly shifting
the breaker point box on its mounting and using a
timing light. If specified timing cannot be obtained by
positioning the breaker box, make sure timing marks
on gears are aligned.

not enough information to answer. gas or propane?. if new,generator by it's very nature generates energy,and thereby heat. even coiled wires can get warm. what part is hot?
if you've owned it a while, and it is inordinately hot as compared to prior uses, is it lubricated ? running normal otherwise?

Make sure all of the vents, on the engine are free of dirt. Check carb adjustment and adjust as needed

go out to the fuse box and find the circuit breaker for that house circuit
switch off and back on to rest it

Finding a manual for a 50-year old diesel generator will be difficult. However, if it needs service I would look online for a commercial service provider who has been in business for many years and is experienced in diesel generators. Look online for generator repair companies. While it's still unlikely they'll have a manual for it, most likely they will still be able to provide service for it. A Google search came up with this site: http://www.dieselenginemotor.com/diesel/engine/Detroit%203-53n%20Diesel%20Engine/3008. Good luck
